We began today with a working loop-the-loop, portions of a post-loop segment and some solid concepts for the lift that would take the bowling ball to the top of the coaster.

We also had huge gaps. With only two days left to work, we focused ourselves entirely on closing the Northern Gap and the Southern Gap and creating a full circuit before we disassemble our Bowler Coaster on Friday.

It's hard to get across how much work our team of 10+ year-olds accomplished today. They built over seventy feet of track, made of hundreds of pieces of wood, connected with thousands of screws.

As of this writing, we have closed the Southern Gap and have one working lift. Tomorrow we'll go for the complete circuit and two working lifts.
